Sanvitalia plant named ‘Duesanyest’

ABSTRACT

A new and distinct cultivar of  Sanvitalia  plant named ‘Duesanyest’, characterized by its compact and mounding plant habit; vigorous growth habit; early and freely flowering habit; and inflorescences with bright yellow-colored ray florets and yellow green-colored disc florets.

Botanical designation: Sanvitalia procumbens.

Cultivar denomination: ‘DUESANYEST’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sanvitalia plant, botanically known as Sanvitalia procumbens, and hereinafter referred to by the name ‘Duesanyest’.

The new Sanvitalia plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact and mounding Sanvitalia plants with numerous attractive inflorescences.

The new Sanvitalia plant originated from a cross-pollination conducted by the Inventor in Rheinberg, Germany in July, 2011 of a proprietary selection of Sanvitalia procumbens identified as code number L09-0712-001, not patented, as the female, or seed, parent with a proprietary selection of Sanvitalia procumbens identified as code number L08-0812-001, not patented, as the male, or pollen, parent. The new Sanvitalia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2013.

Asexual reproduction of the new Sanvitalia plant by vegetative cuttings in a controlled environment in Rheinberg, Germany since June, 2013 has shown that the unique features of this new Sanvitalia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sanvitalia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duesanyest’. These characteristics in combination distinguish ‘Duesanyest’ as a new and distinct Sanvitalia plant:

-   -   1. Compact and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Early and freely flowering habit.     -   4. Inflorescences with bright yellow-colored ray florets and         yellow green-colored disc florets.

Plants of the new Sanvitalia differ primarily from plants of the female and male parent selections in plant habit as plants of the new Sanvitalia are more compact than plants of the female and male parent selections.

Plants of the new Sanvitalia can be compared to plants of Sanvitalia procumbens ‘Talya Great Yellow’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Sanvitalia differed from plants of ‘Talya Great Yellow’ in the following characteristics:

-   -   1. Plants of the new Sanvitalia were more compact than plants of         ‘Talya Great Yellow’.     -   2. Plants of the new Sanvitalia had smaller leaves than plants         of ‘Talya Great Yellow’.     -   3. Plants of the new Sanvitalia had slightly smaller         inflorescences than plants of ‘Talya Great Yellow’.     -   4. Inflorescences of plants of the new Sanvitalia had darker         yellow-colored ray florets than inflorescences of plants of         ‘Talya Great Yellow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Sanvitalia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Sanvitalia plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Duesanyest’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the summer in 10.5-cm containers in a glass-covered greenhouse in Rheinberg, Germany under conditions and practices which approximate those generally used in commercial Sanvitalia production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
